I led design and illustration for OH! San Diego, the San Diego Architectural Foundation's open house festival celebrating architecture, urban design, and the built environment. The work covered the maps, the location guide booklet, and the promotional materials. The booklet moves neighborhood by neighborhood, from Downtown and Balboa Park to Point Loma and Coronado, with clean site listings, maps, photography, and small line icons for sections like historic sites and orchid winners. The accompanying location map poster pairs a photo of the Hotel del Coronado with a color-coded neighborhood map and site index, and the poster ads carry the same photo, the bold yellow OH! mark, and sponsor logos. I produced clean, legible map spreads and cohesive collateral while coordinating print and vendors. The materials enhanced the event experience and attendance.
